The Sleep Suit Sack should be fitted around the neck and the armholes to avoid your child slipping through. In 'legs' mode, there should be enough length at the end of the suit to allow your child to move their feet freely. 2.5 TOG and 3.5 TOG Sleep Suit Sacks should not be used in a 5-point harness or car seat for safety reasons.

We have bought all our sleep sacks from ergoPouch but not a fan of this one. My little one doesn't see like she is comfortable in this sack. Its not breathable and its a pain to zip in middle of the night when changing in the dark.
